my meizu m3 note was working pretty good before updating to flyme6 but after updating i am facing touchscreen issues. Sometimes its working smoothly but mostly screen seems to be touched automatically at 2-3 points i.e. at centre left side of sceen centre and upper left of the screen. Also when I lock and unlock it works fine for some minutes.
Phone is one year and 2-3months older.

Waiting for the right suggestion.
Thanks in advance.
